For split TX/RX operation in “casual” pile-ups, where the split is less than 10 kHz, the TX Clarifier (Offset Tuning) feature
may be utilized.

The Clarifier is frequently used for receiver offset tun-
ing. However, for DX pile-ups where the DX station is
using a split of less than 10 kHz, the TX Clarifier func-
tion is usually the quickest way to set the transmitter to
the desired offset frequency.
2. Rotate the [ CLAR/VFO-B
] knob to set the desired
transmitter offset. A maximum split of ±9.99 kHz may
be set.
3. To exit from TX Clarifier operation, press the [ TX
CLAR
] button once more. The “
TX ” icon will disap-
pear from the Multi-Display Window.

DVICE
:
ˆ When listening to a “pile-up” calling a DX station, in
order to find the station currently being worked, you
may press the [
RX CLAR
] button. Then, use the
[
CLAR/VFO-B
] knob to zero in on the station calling
the DX (use the SPOT function on CW for precise
alignment of your frequency). You may then press the
[
RX CLAR
] button again to cancel the RX Clarifier,
and return to reception on the DX station’s frequency.
ˆ Just as with receiver Clarifier operation, the amount of
offset from the original VFO frequency will appear in
the small display window.
ˆ As with receiver Clarifier operation, when you turn the
TX Clarifier off the last-used offset is remembered,
and will be available if you turn the TX Clarifier back
on. To clear the Clarifier offset, press
the [
CLEAR
] button.
ˆ When you operate on the VFO-B frequency, you may
also activate the Clarifier on the VFO-B frequency.
However, the offset frequency is set using the Main
Tuning Dial knob, instead of the [
CLAR/VFO-B
]
knob.
ˆ The Clarifier operation (including the offset frequency)
will be memorized independently on each VFO stack
of the VFO-A and VFO-B.

:
When attempting to work a DX station on CW in a split
frequency pile-up, remember that a large number of other
stations may also be using Yaesu transceivers with capa-
bility similar to that of your
FT-950 . On the DX side of
the pile-up, everyone calling precisely on the same CW
frequency will sound like a single tone! So you may have
more success if you use the RX Clarifier to find a
hole in
the pile-up, instead of trying to zero-beat the last station
worked by the DX station.
